Outline of Final Research Achievements |
In this study, we found that expression of CDKAL1 - one of susceptible genes for type 2 diabetes and obesity identified in genome-wide association studies - is regulated during adipocyte differentiation, hypertrophy and adiposity. Functionally, CDKAL1 works as a factor that suppresses adipocyte differentiation and lipid accumulation. Mechanistically, we found that CDKAL1 stimulates the Wnt/β-catenin pathway, which suppresses adipocyte differentiation. We also mapped a promoter region responsible for the suppression of adiponectin gene expression in adipocyte hypertrophy. A transcription factor named Heb1 binds and regulates transcription. Expression level of Heb1 itlsef is regulated by various metabolic stress signals in adipocytes.
